Hello World,
Has anyone successfully been able to pair(dial in) a modified 914 L-jet system with a 2200 or 2258? I am looking into doing this for my street car and am aware that the AFM will need to be modified. I have a 52mm throttle body with a modified throttle actuator so the operating arm will work with the L-jet and will fit the stock plenum seal. Will I need bigger fuel injectors than my new 2.0 injectors? If so, which ones? What else do I need? I did a Google search using key words, but was not able to find any previous threads on this topic. Any advice or thoughts would be appreciated. |

That should be a great combo,go to the larger motor and get the most from the larger throttle body ,L-jet can be run on larger capacity motors because the AFM is controlled by airflow and will self adapt to the volume of air working the air gate . Never heard of any modification you can do to them for flow and it's not required,if you have a good AFM don't mess with it , the only one I ever adjusted was to correct " rolling idle" caused by a "hot " street cam in a Golf 2.0 engine I built running cam chip . Pretty certain stock injectors will cover your needs . I recently fitted a 2.0 16V to replace worn out 1.8 16V in my VW Corrado ,I just swapped the old K-jet system from the 1.8 to the 2.0 and it runs and drives very well this system is controlled by airflow also but is full mechanical with a small basic ignition computer however base principal is the same as L-jet . What cam are planning to run ? , believe this would need to be reasonably mild to avoid rough idle which the AFM won't play well with . The sum of all parts in good condition ,the right cam and exhaust should yield a strong motor with good torque , there are most likely some that have done this conversion and can correct me ?,cheers. |
